NCT ID: NCT03592290 Recruiting - Clinical trials for Hemodynamic Instability

Hemodynamics Monitoring During Lower Body Negative Pressure (LBNP) Induced Controlled Hypovolemia

LBPN
Start date: November 15, 2017
Phase:
Study type: Observational

To monitor the changes in central and peripheral monitors/waveforms during gradual hypovolemia induced by lower body negative pressure in healthy volunteers.

NCT ID: NCT03497754 Completed - Hypovolemia Clinical Trials

The Use of an External Ultrasound Fixator (ProbeFixR) on Intensive Care Patients

Soundprobe
Start date: May 17, 2018
Phase: N/A
Study type: Interventional

Study to assess the feasibility of an external ultrasound fixator (ProbeFix)

NCT ID: NCT03468764 Not yet recruiting - Hypovolemia Clinical Trials

Hemodynamic Changes Induced by Alveolar Recruitment Maneuver With Respect to Volemic State in Colon Surgery

RecruVol
Start date: March 2018
Phase:
Study type: Observational

Intraoperative hemodynamic management is important, since even mild variations in circulatory volume can be extremely damaging for patients. Minimally invasive hemodynamic monitoring are not always available or cost-effective, therefore management of fluids is challenging for anesthesiologists. This study aims to assess if, after performance of a lung recruitment maneuver (LRM), standard parameter's variation differs between hypovolemic and normovolemic patients. Patients' volemic state will be assessed with the Vigileo system. Standard monitoring values (heart rate, invasive blood pressure and saturation) will be registered before and after LRMs. A fluid challenge will be performed and the above mentioned parameters will be recorded again, after a second LRM. The study is a prospective observational study.

NCT ID: NCT03349593 Completed - Heart Failure Clinical Trials

Prevalence of Hypovolemia and Heart Failure in Non-cardiac Surgery

Start date: December 1, 2017
Phase:
Study type: Observational

Prevalence of biventricular function of the heart and preoperative level of venous return is not known in non-cardiac non-morbid obese population. The aim of the study is to assess the preoperative function of the heart and status of hypovolemia on the day of surgery.

NCT ID: NCT03338218 Completed - Clinical trials for Hypovolemia Due to Acute Blood Loss

Safety and Efficacy of a 6% Hydroxyethyl Starch (HES) Solution Versus an Electrolyte Solution in Trauma Patients

TETHYS
Start date: February 23, 2019
Phase: Phase 4
Study type: Interventional

The aim of the study is to investigate the safety of a 6% hydroxyethyl starch (HES) solution (Volulyte 6%) versus an electrolyte solution (Ionolyte) in trauma patients.

NCT ID: NCT03278548 Completed - Clinical trials for Hypovolaemia Due to Acute Blood Loss

Safety and Efficacy of 6% Hydroxyethyl Starch (HES) Solution Versus an Electrolyte Solution in Patients Undergoing Elective Abdominal Surgery

PHOENICS
Start date: September 28, 2017
Phase: Phase 4
Study type: Interventional

The aim of the study is to investigate the safety of a 6% HES (Hydroxyethyl Starch) solution (Volulyte 6%) versus an electrolyte solution (Ionolyte) in patients undergoing elective abdominal surgery.

NCT ID: NCT03246425 Withdrawn - Critical Illness Clinical Trials

Influence of Mechanical Ventilation Mode on Arterial Pressure Variations- a Pilot Study

Start date: September 12, 2016
Phase: N/A
Study type: Interventional

Mechanical ventilation has been known to produce changes in the flow of blood through the major blood vessels in the body. These changes may go undetected, but with continuous arterial blood pressure measurements, changes in the arterial waveform can be visualized. Although we know that these arterial pressure variations occur during mechanical ventilation, little is known about the effects of various modes of mechanical ventilation on these changes. The most common modes of ventilation used in ICU are Volume control, Pressure control and Airway pressure release ventilation. Objective We have designed a prospective randomized pilot study to determine the effects of the commonly used ventilator modes on the arterial pressure.

NCT ID: NCT03244891 Completed - Hypovolemia Clinical Trials

Autonomic Challenges From Mild Hypovolemia and Mechanical Ventilation

Start date: June 15, 2019
Phase: N/A
Study type: Interventional

Heart Rate Variability (HRV) analysis has been studied in the critically ill patients although it is affected by several uncontrolled variables in the clinical conditions. The aim of this trial is to measure the effects of mildly reduced central volume and cyclic variation of intrathoracic pressure on the variables frequently used to describe the HRV.

NCT ID: NCT03213574 Withdrawn - Hypovolemia Clinical Trials

Impact of GDT in Robot-assisted Laparoscopic Urological Surgery for Low to Moderate Risk Patients

Start date: December 2017
Phase: N/A
Study type: Interventional

Robot assisted urological procedures are often long surgical cases that can potentially result in complicated postoperative hospital course. The amount of intravenous (IV) fluids administered to patients during these operations fluctuates based on the length of the case, surgical blood loss, hemodynamic monitors, and the discretion of the anesthesiologist. The goal of intraoperative fluid therapy is to maintain optimal tissue perfusion without causing fluid overload. We plan to use a goal directed fluid therapy protocol to optimize fluid status and analyze post-operative outcomes.

NCT ID: NCT03209271 Completed - Hypovolemia Clinical Trials

Hemodynamic Effects of Cold Versus Warm Fluid Bolus

Start date: February 3, 2017
Phase: N/A
Study type: Interventional

Fluid boluses are often administered with the aim of improving tissue perfusion in critically ill patients. It is unclear whether the temperature of the fluid has an impact on the hemodynamic response. The aim of this study is to describe the hemodynamic effects of a fluid bolus with two different temperatures.
